The belief that either Moses wrote the Pentateuch or that it predates the Deuteronomistic History (Deuteronomy – II Kings) is unfounded by the Biblical facts themselves:
(Yet it is clear that Jesus thought Moses gave Israel the Law: “Did not Moses give you the Law,…” John 7: 19). Thus, if the modern critical view of the Bible is correct, then Jesus himself is subject to error.)
Point A: Why do latter books of the Bible totally ignore early Mosaic Laws - such as when Elijah is commanded by God to eat what unclean ravens brought (1 Kings 17:6) - especially when the Law clearly forbids eating that which has been torn by beasts?
1. "You shall be holy men to Me, therefore you shall not eat any flesh torn to pieces in the field; you shall throw it to the dogs." Exodus 22: 31
2. "Also the fat of an animal which dies and the fat of an animal torn by beasts may be put to any other use, but you must certainly not eat it." Lev. 7: 24
3. "He shall not eat an animal which dies or is torn by beasts, becoming unclean by it; I am the LORD." Lev 22: 8)
Some more Biblcial proofs of the LATE creation of the “Mosaic Law” (Pentateuch) is listed below:
Point B: Why did Samuel hesitate to anoint a king over Israel (1 Samuel 8) when Samuel already had Deuteronomy 17: 15?
Point C: Why did Elijah build an altar to Yahweh away from the legitimate central sanctuary?
Point D: Why can Hezekiah quote no “Mosaic Law” for his reform, whereas Josiah does (2 Chronicles 31 to 2 Kings 23)?
Point E: Why does Deuteronomy permit Levites to come to the altar where as Leviticus does not? Link.
